IMPROVEMENT IN QRATES.

Specification forming part of Letters Patent No. 38,317, dated April 28, 1863.

To all whom it may concern:

Beit known thatI, WILLIAM L. MCDOWELL, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Basket-Grates of Coal- Stoves; and I do hereby declare that the fol lowing is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanyingdrawings, making a part of this specification, in which- :1; Figure 1 is a front view, Fig. 2 a top view, and Fig. 3 a vertical transverse section, of a common basket-grate having my improvement applied thereto, like letters indicating the same parts when in the different figures.

The object of my invention is to provide a basket-grate with a draw-bar, which. while not being liable to be accidentally drawn out by the poker in raking the fire, can at any time be instantly and readily withdrawn, as occasion may require, leaving an amply sufficient space in the bottom of the grate for the discharge of its contents, and that can also be more cheaply and easily constructed and applied, and be more durable in use than any of the devices in general service for the purpose.

It consists, substantially as hereinafter described and specified, in a peculiar combination of a slotted draw-bar, with a basketgrate of the usual form.

In the drawings, A is the basketgrate, and B the slotted draw-bar. The grate A is constructed in the usual manner and form in all respects, except that the horizontal and part of thevert-ical portions of the two middle bars, a a, are left out, and the two bars a a outside of the said remaining space are connected together, near the front of the grate, by means of a depressed cross-piece, a which forms a supporting-holder for the front end of the slotted draw-bar B, and that the rear support of the grate-bars is depressed at a point, a directly opposite to the cross-piece a so as to receive and support the rear end of the said slotted draw bar B, substantially as shown in the drawings. The drawbar B is formed to have a slot, 1), in its middle, so as to cause it to produce, when in place in the grate, two bars, 12 b which will correspond with the remnants a a, and supply the place of the two which have been left out, as seen in the drawings. The under side of the front end of the draw-bar B is recessed across at 12 so as to receive within the said recess the beveled ridge (0 of the supporting-piece a and thus permit the upper side of the front end of the draw-bar B, when the latter is in place, to be in the same horizontal plane with the upper sides of the other bars of the grate, while its rear end fits into the depression a, so as to bring this part also of its upper surface into the same horizontal plane, thus supplying the places of the two usual fixed bars, as seen in Figs. 2-and 3. The front end of the draw-bar B has also a hole, I), for the reception of the point of a poker in withdrawing it from the grate while hot.

In operation it will readily be seen that when the draw-bar B is in place in the grate its recess b and the beveled ridge a on the crosspiece a will together keep it from be ing withdrawn in raking the fire; that by raising its front end until its said recess Z1 is relieved from the ridge a it can then be readily withdrawn, and the contents of the grate discharged through the opening left thereby; that in withdrawing the bar its rear end will fall downward, and thus relieve the slot 1) from any obstructionswhich would otherwise lay therein and impede the easy withdrawal of the bar, and that the construction and mode of combination are simple, cheap, and less liable to get out of order than any of the devices in common use for the purpose.

Having thus fully described my improvement in basketgrates and pointed out its utility, what I claim as new therein of my invention, and desire to secure by Letters Patout, is-

Combining the draw bar B with a basketgrate, A, by removing the horizontal and curved portions of the two bars a a of the latter and connecting the two adjacent bars a a together by means of the depressed crosspiece a constructed substantially as described, to serve as a retainingsupport for the front end of the said draw bar B, while its rear end is supported in the depression a with its upper side in the same horizontal plane of the upper sides of the remaining bars of the grate, substantially as described and set forth, for the purpose specified.

WM. L. MCDOWELL.
